What Are the Key Differences Between Anterior Pelvic Tilt and Posterior Pelvic Tilt

What Are the Key Differences Between Anterior Pelvic Tilt and Posterior Pelvic Tilt?

The pelvis plays a pivotal role in connecting the upper and lower body, acting as a central junction for various muscles, including the hip, abdominal, and buttock muscles. Its positioning can either support a neutral, healthy alignment or lead to postural problems and pain when it tilts excessively in the anterior or posterior direction.

Our bodies are incredibly dynamic and adaptive structures, and proper posture and alignment are essential for maintaining overall health and functionality. One aspect of body alignment that can significantly impact our musculoskeletal health is pelvic tilt. Two common types of pelvic tilt are anterior pelvic tilt and posterior pelvic tilt. 

Anterior Pelvic Tilt

 Anterior pelvic tilt refers to the forward rotation of the pelvis, causing an increased arch in the lower back. Several key characteristics define anterior pelvic tilt:

  • Tight Hip Flexors: A primary contributor to anterior pelvic tilt is tight hip flexor muscles. These muscles, including the iliopsoas, attach the thigh bone to the lower back, and when they become overly tight, they can pull the pelvis forward.
  • Lumbar Lordosis: The exaggerated arch in the lower back, or lumbar lordosis, is a hallmark of anterior pelvic tilt. This can lead to discomfort and pain in the lower back region.
  • Muscular Imbalance: A muscular imbalance may develop as the anterior tilt causes the abdominal muscles to lengthen and weaken while the lower back muscles become overactive.

Posterior Pelvic Tilt

On the contrary, posterior pelvic tilt is the backward rotation of the pelvis, flattening the lower back and tucking the pelvis under. The key features of posterior pelvic tilt are as follows:

  • Tight Hamstrings: Posterior pelvic tilt can be associated with tight hamstring muscles. When the pelvis tilts backward, it forces the hamstrings to stretch excessively.
  • Reduced Lumbar Curve: The natural curve in the lower back is diminished with posterior pelvic tilt, and this may result in discomfort and pain in the lumbar spine area.
  • Buttock Muscles and Glute Muscles: In this condition, the buttock and gluteal muscles are often underactive, which can lead to weakness and instability in the pelvic region.

Key Differences Between Anterior and Posterior Pelvic Tilt

  1. Pelvic Tilt Direction: The primary distinction between anterior and posterior pelvic tilt is the direction in which the pelvis rotates. Anterior tilt results in a forward rotation, while posterior tilt involves a backward rotation.
  2. Lumbar Spine: Anterior pelvic tilt often exaggerates the natural curve of the lumbar spine, causing lordosis, while posterior pelvic tilt reduces this curve.
  3. Muscle Involvement: The specific muscles involved also differ. Anterior tilt is associated with tight hip flexors and overactive lower back muscles, while posterior tilt is linked to tight hamstrings, underactive buttocks, and gluteal muscles.
  4. Postural Effects: Anterior pelvic tilt can lead to a “swayback” appearance, while posterior tilt tends to result in a flattened lumbar spine and a “tucked under” appearance.
  5. Potential Issues: Anterior pelvic tilt is often associated with lower back pain and poor posture, while posterior pelvic tilt may cause hamstring tightness and contribute to pelvic instability.

Let's Learn the Impact on Overall Health

 Both anterior and posterior pelvic tilt can have far-reaching consequences for an individual’s overall health and well-being.

 Anterior Pelvic Tilt Issues:

  •  Lower Back Pain: Exaggerated lumbar curvature in anterior tilt can lead to chronic lower back pain.
  •  Poor Posture: Anterior tilt can result in a swayed lower back, protruding abdomen, and a forward head posture, leading to overall poor posture.
  •  Muscular Imbalance: The imbalance in muscle strength and flexibility can lead to pain and dysfunction in the abdominal and lower back muscles. 

Posterior Pelvic Tilt Issues:

  • Hamstring Tightness: Tight hamstrings in posterior tilt can result in discomfort and reduced flexibility in the legs.
  • Pelvic Instability: Weak buttocks and gluteal muscles can lead to instability in the pelvic region, potentially impacting balance and gait.
  • Reduced Lumbar Support: A flattened lower back can reduce the natural support provided by the lumbar spine.

Preventing and Addressing Pelvic Tilt Issues

Both anterior and posterior pelvic tilts can be managed through a combination of exercises, stretches, and lifestyle adjustments. At Pro Cure Physio, we recommend the following strategies to address these issues:

  1. Muscle Stretching: For anterior pelvic tilt, focus on stretching tight hip flexors, while for posterior tilt, concentrate on hamstring stretching.
  2. Muscle Strengthening: Strengthening exercises for the core, glutes, and hamstrings can help address muscular imbalances associated with pelvic tilt.
  3. Postural Awareness: Being mindful of your posture throughout the day can significantly reduce the impact of pelvic tilt. Regularly engage in exercises that promote proper alignment.
  4. Ergonomics: Ensure that your workspace and daily activities support good posture, whether sitting at a desk or standing for extended periods.
  5. Professional Guidance: Scedule an appointment with a physiotherapist to receive a personalized treatment plan tailored to your specific needs. They can use tools like a caliper-based inclinometer to measure pelvic tilt angles accurately.


Anterior and posterior pelvic tilts are common postural issues that can affect individuals of all ages, especially those with tight hip flexors, weak core muscles, and poor posture habits. Understanding the key differences between these tilts is crucial for addressing the associated problems and maintaining overall musculoskeletal health. 

At Procure Physio, we believe in the importance of identifying and addressing pelvic tilt issues to promote a pain-free and healthy lifestyle. By implementing a well-rounded approach that includes stretching, strengthening, postural awareness, and professional guidance, individuals can mitigate the negative effects of anterior and posterior pelvic tilt and move toward achieving a balanced, neutral pelvic position. Remember, the road to a healthier, more comfortable life starts with understanding your body and taking proactive steps to correct imbalances.
